This country has become great by absorbing huge numbers of immigrants. We have a proven system - we know that we can do it. But we all know that the system only works if immigrants assimilate.
We keep hearing that we "should be more like Europe". Especially France. Keep your eye on this. There are a lot of intellectuals here who scoff at assimilation, and a whole lot of "activists" who gain political power if immigrants don't.
An ancient Chinese curse goes, may you live in interesting times. It's getting interesting.
